CONCORD, N.H. (AP) — A traveling medical technician who infected dozens of patients in multiple states with hepatitis C through tainted syringes is finding out how many decades he'll spend in a New Hampshire prison.

Thirty-four-year-old David Kwiatkowski (kwiht-KOW'-skee) has admitted stealing painkillers and replacing them with saline-filled syringes tainted with his blood. He worked in 18 hospitals in seven states before being hired at New Hampshire's Exeter Hospital in 2011.

He pleaded guilty in August to 16 federal drug charges under an agreement that calls for him to spend 30 to 40 years in prison. He is being sentenced Monday.

Thirty-two patients were infected in New Hampshire, seven in Maryland, six in Kansas and one in Pennsylvania. Kwiatkowski also worked in Michigan, New York, Arizona and Georgia.
